Became an Astartes just before the Scourge Campaign in 640.M41. Indoctrinated with an utter belief in the glory of the Imperium and the need for extreme action to maintain the Emperor. First fighting as part of assault force during this Campaign.

Part of force that accompanied Huron to the Lycanthros Drift in 780.M41 and saw there that the other Space Marine Chapters were not as competent as the Astral Claws. Determined this to be because of Huron's extreme tactics.

When the Crusade happened he missed out because he was training the Badab PDF, the units that would later become the Tyrant's Legion guardsmen. When these legions were formed he was given command of a unit as a Centurion. This required him to lead the guardsmen but also to punish them and be a symbol of the Tyrants utter strength.

Tyrant's Legion were obliterated by Fire Hawks in an orbital bombardment of toxins and Harkon was reassigned to a Retaliator unit. Having survived the destruction of his entire unit of underlings he is not in a good mood.
